Pd metal dissolves in anhydrous HF (aHF) acidified with AsF5 in the presence of F2 at ≈298 K to give a blue-green solution from which green Pd(AsF6)2 can be isolated. The latter was also prepared by the interaction of PdF2 and AsF5 in aHF or by the reaction between PdO and F2 in aHF acidified with AsF 5. Powdered Pd(AsF6)2 slowly loses AsF 5 in a dynamic vacuum. It can therefore be isolated from solution at T 6)2 were prepared by solvothermal synthesis from a Pd/AsF5/F2/aHF mixture at 393 K. Pd(AsF6)2 is triclinic with a = 500.9(5), b = 538.3(5), c = 864.9(9) pm, α = 74.46(3), β = 89.97(4), γ = 62.47(2)° V = 0.1972(3) nm3, and Z = 1, space group P1 (No. 2). The six-coordinate Pd atoms (coordinated with fluorine) are well separated by isolated AsF6 units. In the 2-175 K temperature range Pd(AsF 6)2 follows the Curie-Weiss law with μeff = 3.53 B.M., Tn = 8 K and θp = -13 K. Because of cation-anion interactions, the AsF6- anions deviate from ideal Oh symmetry. The reduced symmetry can be seen in vibrational spectra, where splitting of the anion vibrational modes can be observed. The oxidation of Pd metal or PdO with F2 in neutral aHF yielded Pd 2F6. No reaction was observed between Pd, PdO or Pd 2F6 and AsF5 in aHF. All attempts to prepare PdFAsF6 were unsuccessful. Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2004.
Studies of how redox chemistry influences the synthesis of transition metal phosphametallocenes: A convenient synthesis of 2,5-diester-substituted phosphametallocenes and 2,2′,5,5′-tetraester-substituted-1,1′- diphosphaferrocenes

Convenient syntheses of 2,5-diester-substituted phosphametallocenes and 2,2′,5,5′-tetraester-substituted-1,1′-diphosphaferrocenes are described. Studies of the reactivity of alkali metal 3,4-dimethylphospholide, 2-ester-3,4-dimethyl phospholide and 2,5-diester-3,4-dimethylphospholide anions towards iron(ii) centres (as [Fe(AlCl4)2] or [Fe(MeCN)6(BF4)2]) indicate that the corresponding 1,1′-diphosphaferrocenes are obtained without any complications resulting from redox chemistry at the iron centre.

A mild, oxidative fluorination approach to a variety of fluorinated phosphorus compounds using trichloroisocyanuric acid (TCICA) and KF was developed as a complement to a recent study on deoxygenative fluorination using oxalyl chloride. Herein, the syntheses of several fluorinated organophosphorus compounds are reported, and both TCICA/KF and oxalyl chloride/KF conditions are compared and contrasted throughout. Initial investigations of the method on other group 15 heteroatoms (i. e., As, Sb, and Bi) are also reported, with varied success. This work notably extends the known TCICA/KF reactivity series to another group of elements beyond previously studied chalcogens (S, Se, and Te) and halogens (iodine) and expands the utility of the previously reported oxalyl chloride/KF method.
